Embodiment Construction
[0011] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0012] In order to reduce the amount of data when a large number of color images are transmitted and stored, the present invention provides a method for reducing the amount of data transmitted in real time for color images, which mainly includes the following steps:
[0013] According to the camera development instructions, set the color camera to grayscale mode (the grayscale mode in this application file refers to the monochrome raw data mode). Preferably, the color camera is a color CCD camera based on a Bayer template, which can support secondary development.
[0014] Run a color camera to collect images in real time. At this time, the images transmitted and stored to the computer are all single-channel grayscale images (the grayscale images in this application file refer to the original bare data).
[0015] After the acquisition and transmission are co...

The method provides a method for reducing a real-time data transmission amount of a color image, which is used for a color CCD camera to acquire and transmit image data to a computer. The method comprises the following steps: by use of a camera development instruction, setting the color CCD camera to be at a monochromatic original raw data mode (i.e., a gray scale mode); operating the camera to acquire in real time original raw data whose images, transmission and storage are all single channeled; and finishing acquisition and transmission, the computer performing color interpolation calculating on stored monochromatic original raw data to obtain a three-channel color image after each pixel is interpolated. The operation and calculating are simple and feasible, and during a transmission process, a three-channel data amount is reduced to a single channel, i.e., the amount is reduced to be one third of an original amount, so that real-time transmission and storage data amount can be effectively reduced, hardware pressure is relieved accordingly, and the problem of frame loss is solved. Therefore, the method provided by the invention is a simple and feasible method which exerts no effects on data, and can be applied to the field of color image real-time acquisition of a large data mount.
Description
Technical field [0001] The present invention relates to the field of color image transmission technology, in particular to the field of large data volume color image real-time transmission technology. Specifically, the present invention particularly relates to a method for reducing the real-time transmission data volume of color images. Background technique [0002] With the rapid development of electronic technology and CCD (Charge-Coupled Device) imaging technology, high acquisition frequency and high resolution are increasingly used in various fields such as aerospace, industrial control, transportation, and multimedia networks. , Multiple color industrial cameras are collecting images for a long time. At this time, it is necessary to transmit and store a large amount of image data in real time. This places very high requirements on hardware, such as frame grabbers, computer memory, hard disks, etc., and often due to limited transmission and storage capabilities of the hardwar...
